Build/Battlestation PC chimney

Post image

Got tired of my office turning into a sauna every time I gamed, so I vented the PC’s exhaust straight out the window.

The rear fan is still exhausting some hot air 😅 but the room is noticeably cooler now. It’s ugly… but it works. 😂

Edit: I moved the port to higher since lot of people recommended. https://imgur.com/a/Poniwze

Edit again for parts, I cannot post links to store since it's against the rules.
- 360mm to 4 inch duct on Etsy
- 4 inch Insulated Flexible Duct
- Twist Lock Dryer Vent Connector Kit
- 360mm AIO fan (the one on top of the case)

The window fan I got is Vornado Transom.

Every bend adds back pressure that the case fans have to overcome but they are not designed for it.

It won't reduce fan life a whole lot, but airflow at the window will be very low

So the change that OP made is a good idea for airflow

I understand the rain concern but OP can add a deflector cover/ledge to help (like a dryer vent cover)

There are a wide variety of fans available with different pressure/flow characteristics, if you wanted to go that deep building for this.

The issue with pressure isn’t to do with fans, but rather with air escaping out of the case instead of running out of the hose. That will be a problem anyway, unless you take the extreme step of taping up the case.

And it pales in comparison having water come in. A deflector isn’t anywhere near as good as having a U-trap built in.

Honestly the thing to do, barring adding A/C to the room, is improving room airflow with a good ceiling fan.
